What is non- cyclic process ? Show that the area under the `P-V` diagram gives the work done by a system in a non- cyclic process.

What is cyclic process ?

In the indicator diagram shown, the work done in the cyclic process is br>

Verify that the area under the p-V curve has dimensions of work.

What do you understand by cyclic process?

In an isothermal thermodynamical process, the value of work done by a system is

The amount fo heat given to a system in a cyclic thermodynamic process

What is cyclic process ? Prove that the net work done during a cyclic process is numerically equal to the area of the loop representing the cycle.

In cyclic processes, when is the work done positive or negative?

How is work done found using p-V diagram ?

A gas undergoes a change of state during which 100 J of heat is supplied to it does 20 J of work. The system is brought back to its original state through a process during which 20 J heat is released by the gas. The work done by the gas in the second processes.
